CPAP Machine Cleaning Instructions for Patients
Clean your CPAP mask, tubing, and humidifier chamber daily with warm water and mild soap, rinse thoroughly, and air dry completely before the next use; use only distilled water in the humidifier chamber, never tap water. 1
Daily Cleaning Routine
Mask and Headgear
- Wash your mask cushion and frame every morning after use with warm water and mild dish soap 1
- Rinse all soap residue completely and allow to air dry on a clean towel 1
- Wipe down headgear straps weekly with a damp cloth (do not submerge unless manufacturer specifies) 1
Tubing
- Disconnect and wash the tubing daily with warm soapy water 1
- Rinse thoroughly and hang to air dry completely before reconnecting 1
- Ensure no water droplets remain inside before use 1
Humidifier Chamber
- Empty any remaining water every morning and wash the chamber daily with warm soapy water 1
- Rinse well and air dry completely 1
- Use only distilled water in the humidifier—never tap water, as tap water contains minerals and microorganisms that can cause illness and equipment damage 1
Weekly Maintenance
- Inspect all equipment for wear, cracks, or cloudiness 1
- Disinfect the humidifier chamber weekly by soaking in a solution of 1 part white vinegar to 3 parts water for 20 minutes, then rinse thoroughly 1
- Replace disposable filters according to manufacturer instructions (typically monthly) 1
Critical Safety Points
What NOT to Do
- Never use ozone or UV-light cleaning devices for your CPAP equipment—these have not been validated for safety or effectiveness and may damage equipment 1
- Never submerge the CPAP machine itself in water—only the mask, tubing, and humidifier chamber should be washed 2
- Avoid using harsh chemicals, bleach, or alcohol on CPAP components as these can degrade materials 1
Hand Hygiene
- Wash your hands thoroughly before handling any CPAP equipment to prevent contamination 2
- Use alcohol-based hand sanitizer if soap and water are unavailable 2
Replacement Schedule
- Mask cushions: Replace every 1-3 months or when visibly worn 1
- Tubing: Replace every 3-6 months 1
- Filters: Replace disposable filters monthly; wash reusable filters weekly 1
- Humidifier chamber: Replace every 6 months or if cloudy/damaged 1
Warning Signs Requiring Immediate Attention
Contact your equipment provider or sleep physician if you develop:
- New or worsening congestion, runny nose, sneezing, or coughing with CPAP use (may indicate inadequate cleaning or contamination) 1
- Visible mold or discoloration in any component 1
- Unusual odors from the equipment 1
Common Pitfalls to Avoid
- Most patients clean equipment only weekly rather than daily as recommended—this increases infection risk and respiratory symptoms 1
- Using tap water instead of distilled water in the humidifier can lead to mineral buildup and bacterial contamination 1
- Inadequate drying time allows bacterial and mold growth—ensure all components are completely dry before reassembly 1
